Koj paub ntau npaum li cas txog sab hauv LED downlights
LED downlight hais txog lub qab nthab tsom teeb nrog LED ua lub teeb ci. Nws yog ib yam uas tsis yog - lub teeb tseem ceeb thiab niaj hnub hom teeb pom kev zoo ntawm qhov ntsuas tsis tau. Nws tuaj yeem muab tso rau ntawm lub qab nthab lossis sab saud ntawm cov rooj tog zaum, lossis nws tuaj yeem muab tso rau hauv phab ntsa, phab ntsa tiab lossis ncaws hauv kab ko taw, nws tuaj yeem tsim cov khaubncaws sab nraud povtseg thiab muaj yeeb yuj pom kev. LED downlights yuav twv yuav raug hu ua ib tiam tshiab ntawm cov teeb pom kev zoo uas thawj zaug hloov cov teeb pom kev zoo. Nws tsis yog tsuas yog lub zog - txuag thiab ib puag ncig tus phooj ywg, tab sis kuj muaj lub neej ntev thiab ua haujlwm siab. Nyob rau hauv lub neej yav tom ntej, nws yuav sai sai nkag mus rau hauv lub tshav dav hlau teeb pom kev zoo thiab ua rau cov kev hloov tshiab.
1. Qhov rov qab voltage VRm ntawm LED downlight: qhov siab tshaj plaws tso cai rov qab voltage. Tshaj qhov nqi no, LED downlight tej zaum yuav puas los ntawm kev tawg.
2. Qhov voltage ntawm LED downlight: qhov peb feem ntau hais yog rau pem hauv ntej voltage ntawm lub LED qab nthab tsom teeb, uas yog hais tias, lub zoo ncej ntawm lub LED yog txuas nrog lub zoo ncej ntawm lub hwj chim mov, thiab tus ncej tsis zoo yog txuas nrog tus ncej tsis zoo ntawm lub hwj huam mov. Qhov voltage muaj feem xyuam rau xim, liab, daj, daj -ntsuab Qhov voltage yog nyob nruab nrab ntawm 1.8-2.4v. Qhov voltages ntawm dawb, xiav, thiab emerald ntsuab yog nyob nruab nrab ntawm 3.0-3.6v. Tej zaum yuav muaj qee qhov sib txawv ntawm qhov voltage ntawm tib batch ntawm LEDs, uas yuav tsum tau raws li cov chaw tsim khoom. Thaum sab nraud kub nce, VF yuav poob.
3. Cov xim kub ntawm LED downlights: qhia nyob rau hauv qhov kub thiab txias K, uas yog, cua sov tus qauv dub lub cev. Thaum kub nce mus rau ib theem, cov xim pib hloov ntawm tsaus liab - lub teeb liab - txiv kab ntxwv daj - dawb - xiav, thiab maj mam hloov. Thaum cov xim ntawm lub cev dub zoo ib yam, peb hu qhov kub thiab txias ntawm lub cev dub thaum lub sij hawm xim kub ntawm lub teeb ci.
4. Cov xim ntawm LED downlight: Cov xim ntawm LED yog qhov taw qhia tseem ceeb heev, uas yuav tsum tau muab cim rau txhua yam khoom LED downlight. Tam sim no, cov xim tseem ceeb ntawm LED yog liab, ntsuab, xiav, cyan, daj, dawb, sov Dawb, amber thiab lwm yam xim, qhov ntsuas no yuav tsum tsis txhob hnov qab thaum peb tsim thiab tau txais kev txiav txim (tshwj xeeb tshaj yog rau cov pib). Vim tias cov xim sib txawv, cov kev cuam tshuam cuam tshuam kuj muaj kev hloov pauv zoo.
5. The current of the LED downlight: the forward limit (IF) current of the LED is mostly 20MA, and the light decay current of the LED cannot be greater than IF/3, about 15MA and 18MA. The luminous intensity of the LED is only within a certain range and IF In direct proportion, when IF>20MA, kev txhim kho ntawm qhov ci tsis tuaj yeem sib cais los ntawm lub qhov muag sab hauv. Yog li ntawd, nws yog qhov tsim nyog xaiv qhov ua haujlwm tam sim no ntawm LED ntawm 17-19MA.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri- pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag , LED Stadium Teeb, LED High Bay, LED Classing Room Teeb, Yog tias koj xav yuav cov khoom lag luam zoo - LED teeb pom kev zoo lossis muaj ntau yam hauv - kev nkag siab tob ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov tiv tauj xa peb nug.
